The last laws explicitly discriminating against the Chinese were gone around 2001. Anti-Chinese and anti-Asian discrimination continues unabashed.

In fact, Chinese-Americans are ahead of most European-Americans. https://en.wikipedia.org/wiki/List_of_ethnic_groups_in_the_United_States_by_household_income
